44 个常见问题解答
对于EVOS成像系统而言：
•确认灯已打开（很容易检查：在载物台上放一块薄纸）
•确认样品不要太混浊；与校准载玻片或其他薄的单细胞样品载玻片进行对比。
•检查物镜，确认物镜转轮对齐并且物镜完全转动到它的位置。
•对于EVOSFL成像系统：移动光立方的位置
•对于EVOSFL Auto成像系统：检查所有的USB端口，确保显微镜与电脑连接。
• 对于明场设置，检查聚光镜滑块位置，确保聚光镜滑块在预定的位置。
当在Z轴（上和下）聚焦得太高时，物镜会擦到容器支架适配器。这是EVOS FL Auto成像系统启动、仪器启动时移动载物台或切换物镜时遇到的特殊问题。盖玻片矫正物镜的镜筒顶部更加宽和平，尤其是在样品容器边缘成像时，这意味着它们更容易触碰容器支架适配器的边缘，在这些情况下，无法使用物镜在这些区域成像。如果物镜被容器支架适配器‘’卡‘’住了，慢慢的旋转容器支架适配器上的拇指螺丝，将其竖直提起离开载物台，然后再朝着载物台的中心向下移动物镜聚焦。最好的办法是在您的实验室设定一个关机流程，包括将物镜移动到最低的放大倍数，在每天关闭仪器之前向下调整镜头。
物镜镜头在与容器支架适配器的刮擦时会严重损毁。如果发生刮擦，取出物镜，仔细检查物镜——尤其是镜头——是否损坏。

Yes. The FLoid device is designed to operate like a molecular biology gel documenting station. You simply walk up and, after a few clicks and a few moments, you walk away with a credit card-sized printed image that you can peel off and place directly into your lab notebook.
This can be done easily. The FLoid device has built-in image processing so you can quickly adjust the brightness and contrast of your images. You can also display images in color or black and white.
Yes. The scale bar changes as the digital zoom level is changed, allowing easy estimation of sample sizes.
The FLoid device is primarily operated through a graphical user interface, much like a smart phone. You focus on the sample with the turn of a knob.
Focus assist is a gauge designed to aid in rapid focusing and to help reduce the feeling of being "lost" while trying to focus on a sample with the FLoid Cell Imaging Station. The scale bar displays a number based on the position of the objective lens. That number can be correlated with a particular sample vessel, allowing you to focus on a sample in that sample vessel more quickly in the future.
For the EVOS imaging systems:
Make certain the light is on (easy way to test this: place a piece of thin paper on the stage).
Make certain the sample is not too opaque; compare with a calibration slide or another, thinner or single-cell sample on a slide.
Check the objectives to make certain the turret is in alignment and the objective is completely threaded in its slot.
For the EVOS FL Imaging System: change the position of the light cubes.
For the EVOS FL Auto Imaging System: check the insertion of all USB ports for connectively from scope to computer.
For brightfield settings, check the condenser slider slot; make certain the condenser sliders are completely in place.

Objectives can hit the vessel holder when they are focused too high in the Z axis (up and down). This is a particularly a problem with the EVOS FL Auto Imaging System during instrument start-up, when the stage moves during system initiation, or when changing objectives. Coverslip-corrected objectives tend to be wider and flatter at the top of the barrel, which means that they are more likely to run into the edges of the vessel holder, particularly if you are imaging at the edges of the sample container. In those cases, use of that objective for those areas of the container may not be possible. If the objective if “jammed” by the vessel holder, then carefully unscrew the thumbscrews of the vessel holder and lift it straight off the stage, then move the objective downward in focus and toward the center of the stage. It is a good idea to have a shut-down procedure in your lab that includes moving the objectives to the lowest magnification and focusing downward with course focus prior to turning off the instrument for the day.
An objective can be damaged by scraping against the vessel holder. If this happens, take out the objective and examine it carefully for damage, particularly on the lens.

You should choose based upon the complexity of your labs' analyses and whether you need transmitted (color) camera imaging or fluorescent (monochrome) camera imaging, or both. At routine/basic analyses, we offer the EVOS XL Core Imaging System for simple transmitted light imaging (typically used in cell culture facilities) or the FLoid Cell Imaging Station for dedicated three-color fluorescence imaging. The EVOS XL Imaging System differs from the EVOS XL Core Imaging System in that it has a larger monitor, a five objective turret (only four objectives with the EVOS XL Core instrument), can be networked, and can perform cell counting.
If you need more options for fluorescent wavelengths, cell counting, or time-lapse imaging, you may consider the EVOS FL Imaging System or the EVOS FL Auto Imaging System. The EVOS FL Auto Imaging System is our most versatile option, featuring automated imaging and more. It has both color and monochrome camera options, and can even be paired with our EVOS Onstage Incubator system.
